Abstract—

In this article, the octamethylcyclotetrasiloxane is introduced into ethylene glycol. The reaction is terminated using acrylic acid to obtain a linear polydimethylsiloxane intermediate comprising double bonds at the ends. The targeted copolymer is prepared by copolymerizing polydimethylsiloxane intermediate and butyl methacrylate. Additionally, blended-porous film is prepared by adding the copolymer to the cyclodextrin copolymer. The results reveal that the thermal stability of the copolymer increases with the increase of the polydimethylsiloxane content. The ethanol solution of the copolymer of a certain formulation has temperature sensitivity. The contact angle hysteresis of cyclodextrin copolymer is larger on the inclined surface at five degrees from the horizontal, but the blended-porous films all have low contact angle hysteresis, and the minimum contact angle hysteresis decreased to 2°. The main reason for the observed difference is that the presence of the copolymer makes the surface morphology of the film changed greatly. The blended-porous films have a waterproof and easy-to-slide surface.

乙二醇-聚二甲基硅氧烷-聚甲基丙烯酸丁酯共聚物的合成与表征

摘要:本文将八甲基环四硅氧烷引入乙二醇。用丙烯酸终止反应，得到在末端含有双键的线性聚二甲基硅氧烷中间体。目标共聚物由聚二甲基硅氧烷中间体和甲基丙烯酸丁酯共聚而成。此外，通过将共聚物加入到环糊精共聚物中制备混合多孔膜。结果表明，共聚物的热稳定性随着聚二甲基硅氧烷含量的增加而提高。某配方共聚物的乙醇溶液具有温度敏感性。环糊精共聚物的接触角迟滞在距水平5度的倾斜表面上较大，但混合多孔膜的接触角迟滞都很小，最小接触角迟滞降至2°。所观察到的差异的主要原因是共聚物的存在使膜的表面形貌发生了很大的变化。混合多孔膜具有防水和易滑动的表面。
